Interior wall board connection



May 12, 1931. MCCHES'NEY I 1,804,630 Q It INTERIOR WALL BOARD CONNECTION Filed May 19, 1950 x97 TOR/V575 Patented May 12 1931 r v UNITED STATES PATENT OFFICE INTERIOR WALL BOARD CONNECTION Application filed May 19,

My invention relates to improvements in lnterior wall board connections, and the object of the invention is to devise simple adjacent verticals forming the interior cor ner of a compartment. 3 and 4 are wall board portions which it is desired to secure to the supports 1 and 2 to form the room corner. The board 3 is provided with an edge recess 5 and the endof the wall board portion 4 is cut to the required length to fit against the inner edge of the wall portion 3 and against the supporting member 1 and at right angles to the portion 3.

6 is a metallic strip or plate one arm of which fits and is counter sunk within the recess 5 and extends beyond the end of the portion 3 and against the end face of the board 4 into contact with the supporting member 1. The other arm extends at right angles to the aforesaid arm between the supporting structure 1 and the wall board 4.

The wall board 4 is secured in position by a nail 7 which is driven through the wall board and intervening portion of the plate 6 into the supporting structure 1.

The nail 7 may be slightly counter sunk at its head and the orifice filled with a plastic filling such as indicated at 7 The other arm of the plate 6 fitting in the recess 5 is secured by means of an ordinary nail 8, the head 8 of which bears against the outer face of the plate arm and is counter sunk within the recess 5 such recess 5 is then filled with a plastic filling 9 so that the contained por- 1930.

tion of the plate 6 and the head 8* are covered and a fiushsurface formedaround the corner of the joint.

It may be pointed out that this construction is particularly adaptable for forming a corner connection between the vertical walls and the ceiling. In many cases, due to various causes, the walls sink and tend to break away from the ceiling. By my construction the angle plate secured to the wall extends above and behind the wall board of the ceiling so that any tendency for the wall board of the wall to drop will draw the wall board of the ceiling with it so that there is no' tendency for one to break or crack away from the other.

From this description it will be seen that I have devised'a very simple form of interior corner connection which will provide a perfectly smooth outer face rendering the joints invisible and permitting the surface to be papered or painted without the joints being visible to the slightest extent.

What I claim as my invention is:

The combination with a supporting structure, a wall board portion provided with a recess in its inner face extending from the edge thereof and a wall board portion cut to the required length and set at right angles to the aforesaid wall board portion so that its end is opposite the recess thereof, an angle member or plate one arm of which is counter sunk within the recess and fits the end face of the adjacent wall board portion, the other arm extending between the adjacent wall board portion and the supporting structure, a securing nail extending through each wall board portion and the angle plate into the supporting structure the heads of which are counter sunk, and a filling for the 9 recess covering the head of one nail and for the orifice formed by the counter sinking of the head of the other nail.
